What is Casting Couch? It’s a column that’s trying to talk about casting news on a day when Oscar nominations are king. Pity it. Paul Thomas Anderson is the sort of filmmaker who casts amazing actors in his movies and then directs them to the best performances of their careers. From Philip Baker Hall in Hard Eight, to Tom Cruise in Magnolia, to Daniel Day-Lewis in There Will Be Blood, to Joaquin Phoenix in The Master, this has always been true. According to Showbiz 411, Robert Downey Jr. may be adding his name to that list soon. They say that he and possibly Charlize Theron are looking like they’re going to be the stars of Anderson’s upcoming adaptation of reclusive author Thomas Pynchon’s novel, Inherent Vice. If this ends up being true it would, of course, be completely awesome for film fans, and probably be the biggest thing that’s happened to Downey’s career since he got cast as Iron Man. That’s a win-win for everybody.
